The front will remain south of long island through the end of the weekend and into early next weak as a series of lows travel along the frontal boundary.

Synopsis
A cold front will move across the region later today and
tonight. The front will remain south of long island through the
end of the weekend and into early next weak as a series of lows
travel along the frontal boundary. Meanwhile, high pressure over
the canadian maritimes will build down along the northeastern
seaboard. High pressure gets closer to the local region Monday
into Tuesday next week. A frontal system from the west moves
across Wednesday into Wednesday night with high pressure
returning thereafter.

Near term until 6 pm this evening
*flash flood watch for NE nj from 2pm til midnight.*
a weak shortwave trough, axis over the eastern great lakes,
will slowly sink southeast today into tonight. At the surface, a
stationary front over central ny, will slowly slide SE into the
region this afternoon and then sink just southeast this
evening.

Isolated shower thunderstorm activity through early afternoon
is expected to become more numerous in the vicinity of the
front as it sinks into the lower hud valley early this afternoon
and then through nyc nj metro and S ct late this
afternoon evening, and then LI this evening.

Main threat today will be areas of urban and poor drainage
flooding and localized flash flooding, as a 45 degree steering
flow to the cold front is not overly conducive to training of
storms. Highest threat of flash flooding will be across the ne
nj river basins where FFG values are extremely low (only 1 2
inch hr), as such a flash flood watch continues through
midnight.

Breaks of Sun and dewpoints in the lower to mid 70s ahead of
the cold front should allow for marginal to locally moderate
instability development. Deep layer shear is marginal at best
and unidirectional westerly (somewhat perpendicular to the cold
front), so not looking at an organized severe threat, but a few
strong to marginally severe storms with wet microburst
potential exists into this evening.

Temperatures today will climb into the lower to mid 80s (upper
80s across nyc nj metro) with dew points remaining in the lower
70s to 75. Heat indices are expected to top out in the lower
90s across nyc nj metro, below heat advisory criteria.

There is a low to moderate risk for the development of rip
currents at the atlantic ocean beaches today.

Short term 6 pm this evening through 6 am Sunday
The cold front move across the area tonight, with showers and
thunderstorms possible through at least midnight. Again, pwats
remain high until the front passes through, so any precipitation
may be locally heavy at times.

Any threat of thunder and heavy showers should come to an end
across much of the region after midnight, but potential that
locally heavy shower and embedded thunderstorm activity could
linger into the overnight across LI nyc as the cold front sinks
just south of the area and a wave of weak low pressure tracks
east along it.

Lows tonight fall into the 60s to near 70. A mav met blend was
used.

Long term Sunday through Friday
Cooler and a little less humid conditions expected to start out
Sunday through Monday with more rain in the forecast Sunday and
Sunday night as the region gets more NE flow. Airmass warms up
for mid to late in the week, near normal levels with winds
having more westerly and southerly components.

Upper level trough will be slow to exist for the close of the
weekend. Trough axis will be west of the region Sunday and
Sunday night with jet streak across the region. The trough axis
moves across Monday. The steering flow will not promote the
front to move farther south of long island and with weak low
pressure areas forming along it, essentially keeping some rain
showers in the forecast for the region, highest chances along
the coast.

More drying takes place Monday when more ridging aloft and high
pressure at the surface will settle more southwestward along
the northeastern seaboard. Dry conditions remain until midweek
when the next frontal system approaches from the west. Aloft, a
large amplitude trough will be approaching with a stronger
southerly jet ahead of it. This jet moves in Wednesday night
into early Thursday. Chances for showers return Tuesday
afternoon and Tuesday night with highest chances N W of nyc. The
chances for showers continues Wednesday with thunderstorms
possible as well as instability is forecast to increase again
with the airmass getting warmer and more humid. Dry conditions
return Thursday into Friday next week with high pressure
returning.

There is a moderate risk for the development of rip currents at
the atlantic ocean beaches Sunday.

Aviation 14z Saturday through Wednesday
A cold front approaches today, and moves across the region this
evening.

Vfr through early afternoon. Tstms with MVFR and brief vsby
reductions to ifr in heavier rainfall move through in the latter
half of the afternoon. Timing may be off by 1-2 hours. A return to
vfr behind the tstms before lowering back to MVFR overnight with
additional -shra possible for city terminals and kteb kisp.

Sw-wsw winds around 10 kt bcmg w, possibly wnw in near tstms. Tstm
gusts may exceed 25 kt in tafs. Nw-n winds behind the cold front
early this evening around 10 kt.

Outlook for 12z Sunday through Wednesday
Sun Potential for MVFR conditions in shra and NE winds of
8-12kt.

Mon-tue Vfr.

Tue night-wed Chance of shower TSTM with MVFR conds.

Marine
Winds and seas remain below SCA levels through tonight across
the forecast waters. Any showers and thunderstorms that move
across the waters will be capable of producing gusty, erratic
winds, chaotic seas and reduced visibilities in heavy rain.

Sca conditions are possible on the ocean waters Sunday as winds
and seas increase. Some marginal SCA wind gusts are possible
for non-ocean waters with otherwise sub SCA conditions expected
for all non-ocean waters. Then, sub-sca conditions are expected
for all the forecast waters early into the middle of next week
but there is a possibility the SCA seas could linger into Monday
for the ocean. Ocean seas could reach SCA criteria again
Wednesday night into Thursday.

Hydrology
*flash flood watch for NE nj in effect from 2pm til midnight.

Main threat today will be areas of urban and poor drainage
flooding and localized flash flooding, as a 45 degree steering
flow to the cold front is not overly conducive to training of
storms. Highest threat of flash flooding will be across the ne
nj river basins where FFG values are extremely low (only 1 2
inch hr), as such a flash flood watch continues through
midnight.

There is a low probability that this flood threat could
continue into the overnight for nyc and li.

Otherwise, no significant rainfall is expected from Sunday through
the end of the forecast period.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
